She is based on Ruben Lagus, the commander of Finnish Armoured Division during the Continuation war and the first recipient of Mannerheim Cross.

As a secretary she often points out how important it is to train and not to slack off - a reference to how all the other Finnish troops mostly concentrated on miscellaneous chores during the three and a half years of the so called "Trench warfare phase" of Continuation War while the Lagus' Armoured Division constantly kept up their combat readiness by training.
